ABSTRACT:
Process for the production of a matrix of electronic components.
The matrix and the associated control circuits are produced in redundant form. The redundant elements can be interconnection lines between the electronic components of a matrix row or column and the associated control circuits or the actual electronic component. A row or column of electronic components represents a subassembly, which is tested by means of optical addressing, consisting of transmitting light rays onto photodiodes located at the periphery of the matrix and connected to each subassembly. As a function of the test result, the matrix is reconstituted by disconnecting the defective electronic components in the redundant subassemblies and then reconnecting the satisfactory subassemblies to one another. This process is more particularly applicable to a matrix of elements used for the control of a matrix display.
